[rocketmouse at archlinux ~]$ bpm2ms 90 | grep 1/32
(60000ms/90BPM)*4*(1/32)= ~83.33333333333333333333ms

So this would be 1/32 note at 90 BPM. This is something a musician
should notice, let alone that artists are not seldom "freaks", e.g.
savants, autists etc., some even without being aware to "suffer" from
autism or something similar.

>But brain might be cheating in assuming having played

We are at least aware of what was played already before, what already
is "processed" by the brain. So I wouldn't it call it "cheating", but
what we are doing is based on "extrapolation". You were to late, the
brain takes a while to notice this and then you compensate it. A good
musician isn't to late, a beginner often is out of time.
